Dry Ingredients
- ½ cup old-fashioned oats
- 1 cup all-purpose flour
- 2 tsp baking soda
- 2 tsp ground cinnamon
Wet Ingredients
- ½ cup unsalted butter
- ½ cup granulated sugar
- ½ tsp pure vanilla extract
- ½ tsp salt
- 2 large eggs
- ¼ cup apple juice, or water
Mix-ins & Toppings
- ¾ cup pecans, finely chopped and divided
Glaze
- ¾ cup powdered sugar
- 1 Tbsp milk
Directions

- Preheat the oven to 350°F and grease a 9×13 baking dish or line it with parchment paper.
- Prepare the apples: In a large bowl, toss the diced apples with 1 tablespoon lemon juice and set aside.
- Mix dry ingredients: In a separate medium bowl, whisk together oats, flour, baking soda, and cinnamon. Set aside.
- Cream the butter and sugar: In a large bowl, use a mixer to beat the butter and granulated sugar until fluffy and pale—about 2–3 minutes.
- Add eggs and flavorings: Mix in the eggs one at a time, followed by the vanilla extract and salt. Blend until smooth.
- Add apple juice: Pour in the apple juice (or water) and mix briefly.
- Combine ingredients: Gradually add the dry mixture to the wet, stirring gently until just incorporated. Then fold in the prepared apples and ½ cup of the chopped pecans.
- Bake: Pour the batter into the prepared dish and spread evenly. Sprinkle remaining ¼ cup of pecans on top. Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
- Cool and glaze: Allow to cool for at least 15 minutes. While cooling, mix the glaze by whisking together the powdered sugar and milk until smooth. Drizzle over the bake before serving.
